• Resumen

  • The vast quantity of waste materials accumulating throughout the world has been creating a costly disposal problem. More than 95% of asphalt pavement materials (by weight) consist of aggregates. The highway and construction industries consume a huge amount of aggregates annually causing considerable energy and environmental losses. As a result of the increasing demands for new aggregate quarries, the general texture of earth’s surface has been steadily deteriorating, causing environmental concerns. The use of marble wastes from marble quarries as aggregates might help meet the increasing demands and slow down any detrimental effects on the environment. In this study, marble aggregates (M) produced from homogeneous marble quarry wastes in Afyonkarahisar Iscehisar region were compared to control aggregate specimen (C) currently used in Afyonkarahisar city asphalt pavements. Various physical and mechanical aggregate tests, Marshall stability-flow and indirect tensile tests were carried out on the aggregates and hot mix specimens and the test results were compared with control specimen (C). The results indicate that the physical properties of the marble aggregates are within specified limits and these waste materials can potentially be used as aggregates in light trafficked asphalt pavement’s binder layers.
